|Issue Date:||2010||Citation:||Luo, J., Zhao, B., On Chan, H.S., Chi, C. (2010). Synthesis, physical properties and self-assembly of star-shaped oligothiophenes-substituted and fused triphenylenes.

ScholarBank@NUS Repository. https://doi.org/10.1039/b918671a||Abstract:||A series of star-shaped oligothiophene-attached and fused triphenylenes was synthesized. The synthesis was first conducted by six-fold Pd-catalyzed Stille cross-coupling reactions to yield the hexakis-oligothiophenes substituted triphenylenes TTP, TTP1, TTP2 and TTP3 and then followed by successful oxidative cyclodehydrogenation of TTP1 to generate the thiophene-fused triphenylene compound TTP1-C with an extended core. Their optical, electrochemical, thermal properties and self-assembly behaviors were investigated and the structure-property relationships were established, which clearly demonstrated the influence of the length of the peripheral oligothiophene units and the core structure on the electronic nature and solid-state packing of these star-shaped disc-like molecules. © 2010 The Royal Society of Chemistry.||Source Title:||Journal of Materials Chemistry||URI:||http://scholarbank.nus.edu.sg/handle/10635/77196||ISSN:||09599428||DOI:||10.1039/b918671a|
